IMPROVEMENT IN MlLLSTONE-FEEDS.

Specificacion forming part of Letters Patent N0. 133,288, dated. November 26, 1872 antedated. November T0 all whom z't mag] concern:

Be it known that I, J OHN WESLEY ANDER- SON, of the town 0f Portland, in the cou11ty of J ay and. State of Indiana, have invented a new and. useful Improvement: in Machines for Feedin g Grain, Middlings, &c., into Millstones; and I d0 hereby declare that the following is a clear, full, and exact description of the 0011- struction am]. operation of the same,referenee being had to the annexed drawing making a part 0f this specifieation, in which-- Figure 1 is a perspective view, and Fig. 2 is a sectional view.

A is a sheet iron hopper, supported by a. cast-iron circular bottom piece, B. This casting 01 bottom piece is made With a. rim 013 flange to support the hopper, a-nd turns inward abrupt-ly g1t S, forming a seat f01 the wheel F t0 run on, and then runs downward in a tubular shape as far as G. 011 the bottompiece B rests a wheel, I, which is made With rin1 and spokes er arms, and a hole through the center, through Which runs the Ela-msel I, which giv es inotion 130 the machine. 011 the lower side of the center 0f the wheel F is suspended a cone, E,With the base enough smaller than the inside 0f the tubular part of the bottom piece B '00 permit the grain, middlings, &c., 110 pass down between them. Over t-l1e tubular part 0f l;he bottom piece B is a. loose sleeve, D P. From the bottom 0f thetube O this sleevetapers inward, as shown ab P, Fig. 2, f0rming a circu1ar opening about the size of the base 0f the cone E. When the sleeve D P is up 110 the highest p0int ehe cireular opening in the bottom just touches the base 0f the cone E. By lowering t11e s1eeve D P an opening is formed. between its narrowest pa-rt and ehe base of the cone E, through which 1:110 grain, middlings, &c., ca-n pass down. By lowering or raising the sleeve D P, thereby increasing or diminishing the open ing, the feed is regulated ab will. I hold the s1eeve in its place by three spiral s1ots, resting 011 pins, as shown ab X, Fig. l, with a set-screw 150 hold 112 at any desired. point, a.s shown ab V, Fig. l; but it may be held, and raised, and lowered by a forked lever or zmy other eonvenient device. Attached t0 the whee1, and projecting above and belowit, are one or more iron rods,

G and M, which keep the middlings, &c., con stantly stirred up and prevent the clogging 01' chokin g 0f ehe machine. The rim 0f the wheel F and ehe seat S, 0n which i1: runs, are cast 011 chills, making them very hard and preventin g them from cuting 0r wea.ring rapidly. The ma'chine is supported by iron legs H holted t0 the bottom piece B and. hopper A. A tube 01 dead-eye, K, is suspended. from the 1egs H by the hangers L.

The operation of the machine is as follows: The open 01' spoked wheel F, in combinat-ion with tl1e cone E and rods 01 stirrers G and M, turns around in ehe grain, middlings, &c., keeping them stirred up, aud forcing them through the opening in the sleeve D P, the quantity being regulated by lowering 01 mising the s1eeve D P, thereby increasing 01 diminishing the opening. The dead-eye K couducts the middlings, &c., into the eye of the stone, and prevents them from sticking to 'the sides and choking the eye 0f the slbone.

VVhat I cla.im as my invention is l. 'Ihe metallic botton1 piece B, consisting 0f the flaring rim 0x fiange, the seat S, and the tubular case O, in combination with theopen wheel F, substantial] y as and for the purpose sei; forth.

2. The combination and arrangement of the tubula.r case O, tapering s1eeve D P, und cone E, substantially as and f0r the purpose described.

3. Incombination with the open wheel F, the gone E, substantially as specified, and for the purpose set forth.

4. In combination with the open wheel F and. cone E, the stirrers G M, substantially as am]. for the purpose described.

5. In combination with the taperin g sleeve D P, the dead-eye K, supported by hangers L and legs H, substantially as and f0r the pur pose spe0ified.
